I don't think its wrong, its just stretching the truth. Kids know its a machine, but believe that its sensitive to noise.
Now looking back at a machine - it has microphone, and sound card. So the input mechanism is in place, the only missing bit is the logic that determines machine's reaction to stimuli.
Without the scrip, the machine cannot be "upset by the noise", but with the script it actually can be, IMHO. So there is some grain of truth in what the guy is saying to his kids...
